The invention is a method to prepare multi-halogen substituted terephthalonitrile. The halogen substituted terephthalyl chloride, molecular formula C1OC-C6HnX4-n-COCl, and liquid amine react to produce halogen substituted terephthalyl amine, then which forms the halogen substituted terephthalonitrile by dehydration. The above reaction can be one-step synthesized. In the formula, n=0.3, X=F, Cl or Br. |
